Each sensor will have a single zone of protection each up to a maximum of 100 metres in length. Each zone will have two or, in high security applications, four tubes joined at one end to the compensating valve and at the other to the sensor.
By linking multiples of this basic configuration any length of perimeter can be protected. The sensors, up to a maximum of 64, are connected to a common 4 core cable and integrated into an MX2000 Multiplex system, which can also monitor many different technology sensors should the site require alternative forms of protection.
